The symbol of Bromine is Br and number of protons(or atomic number) which is also equal to the number of electrons is 35
The symbol for copper is Cu, and it has 29 protons in one atom.
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
The sum of the neutrons and protons is the mass number (A)In this problems,the answer for mass number of mercury isotope is:80 protons + 120 neutrons = 200
The number of protons is the element's c) atomic number.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The number equal to the total number of protons in the elementAtomic number:It is the following number in the Periodic Table, and by definition equal to the number of protons of the atom of that unique element.Example:Hydrogen, atom symbol H, number 1, protons: 1Carbon, atom symbol C, number 6, protons: 6Uranium, atom symbol U, number 92, protons: 92
The symbol for copper is Cu, and it has 29 protons in one atom.
80 protons
O and 8 protons
Kr and 36 protons
The number of protons is different.
262107BHJust imagine the 262 is directly above the 107, the upper number is the atomic mass number which is the sum of the number of protons and neutrons while the lower number is the atomic number which is just the number of protons.
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.
The number of protons of an atom is equal to its atomic number, and element number 79 is gold (Au).
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
The atomic number tells you the number of protons the atom of an element has. The atomis is the smaller of the two numbers next to symbol of the element.
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
